DEVICE FOR NON-REFILLABLE BOTTLES.

Specification of Letters Patent.

Patented May 7, 1907.

Application filed May 18,1906. Serial Nv 317.486.

' filling, so that inferior qualities of liquids may not be substituted for the higher priced contents.

The device, forming the object of the present invention is made preferably of glass and is so cheap that it should be broken up after its use in a bottle in order to avoid attempts to use it again in other bottles. It consists essentially in a valve-casing made of two symmetrical parts which are firmly secured in the bottle-neck and which are provided with lateral outlet ports having at the lower end a valve-seat for a ball which easily opens when the contents should be poured out, and which closes automatically when an attempt is made to refill the bottle.

In the accompanying drawing. forming part of this specification: Figure 1 shows a bottle with the new device partly in elevation and partly in section. Fig. 2 is a vertical section through the bottle-neck and valve- Fig. 3 is a cross-section on line :r-x

casing. Fig. 2.

The valve-casing, inserted in the neck of the bottle is made of two symmetrical parts a made of glass, china or other material to be found and each half has in its upper half a transverse opening or outlet b. The lower part is provided with a valve seat for a ball 0. The valve easily opens when the bottle is inclined to pour out some of the contents and readily closes when an attempt is made to refill the bottle partly by the pressure of the liquid which enters through the parts 5 into the chamber of the valve-casing, and partly by the inclination of the bottle which it must assume for refilling.

The ports I) are made preferably perpendicular to the longitudinal axis of the valvecasing in order to make it impossible to remove the ball 0 from its seat by a concussion of the liquid fraudulently introduced above the device. As a blow or jerk on such liquid when entering through the ports I) is immediately broken.

In order to admit air into the valve chamber when pouring out the liquid, the walls are provided with longitudinal depressions d which cannot be closed by the ball. The valve-casing is provided with a deep annular groove e on the outside. The bottle-neck may be provided with a similar annular groove f or may be left smooth. The space of the grooves e and f is filled with a mass 9 of plaster of paris, putty or the like which prevents a withdrawal of the valve from the bottle-neck. Longitudinal grooves extend along the outer surface of the valvecasing from the top to the space between the grooves e and f, so that the material 9 can be inserted more easily.

The outer surface of the lower part of the valve-casing is preferably made conical anda tightening gasket 6 which may be made of cork, rubber or any other closing material between the conical surface and the glass of the bottle neck prevents the liquid to come in contact with the cementing material, g.

When using the new device the packing i, of cork is first inserted and any suitable cement may be used to stick it fast to the glass. Now the bottle is filled with the true contents and the two halves of the valve casing, inclosing the ball, are tightly pushed into the packing t. Hereafter the cementing material g is packed in the space between the grooves e and f surrounding the valve-casing and sealing the latter permanently into the bottle when perfectly dried.

The upper mouth of the bottle-neck may be now closed with an ordinary cork and the device is ready for use.

The glass of the valve-chamber is made very thin in the middle part where the groove (1 is provided so that it is impossible to draw the valve-casing without breaking out of the bottle in order to make use of it again in other bottles. Even by breaking the neck of the bottle carefully, it would not be possible to recover the valve casing uninjured.

The device is so cheap that it is intended to supply it anew for every bottle and the old ones should be broken up in every instance.

Having thus described my invention, what I claim is:

1. Device for preventing the refilling of bottles which consists of a valve casing formed of two symmetrical halves molded of a plastic material, having a closed cylindrical chamber, a ball 0 in said chamber, a valveseat for the ball a at the bottom, said casing having two opposite lateral outlet openings 1) near the top perpendicular to the longitudinal aXis and having longitudinal lateral depressions d on its inner surface and longitudinal depressions h inits outer surface, said casing being adapted to be sealed permanently to the neck of a bottle substantially as described.

2. Device for preventing the refilling of bottles which consists of a valve-casing formed of two symmetrical halves molded of a plastic material, having a closed cylindrical chamber, a ball 0 in said chamber, a valveseat for the ball 0 at the bottom, said casing having two opposite lateral outlet-openings 7) near the top perpendicular to the longitudinal axis, and having the lower part in the shape of a cone for the insertion into a frustoconical packing and being provided in about the middle with a deep annular groove a to reduce the thickness of the'glass and to receive a cementing material serving to seal permanently the valve-casing into the bottleneck, substantially as described.

In testimony whereof I a'ffiX my signature.
